The Girls star will come between Homer and Marge during Sunday's season 27 premiere of The Simpsons—well, her character, Candace, will. In the episode, the animated couple will attempt a trial separation, during which he will start dating the twenty-something.

Dunham is bringing along her Girls costars for the fun, as Allison Williams, Zosia Mamet and Jemima Kirke also lent their voices to the long-running Fox hit.

In the episode, Homer will fall for Candace, a pharmacist, while filling his prescription for his narcolepsy medication (yes, that's a new diagnosis). E! News has an exclusive sneak peek at the episode, in which Candace and Homer exchange flirty banter about his hairdo.

The storyline made waves when showrunner Al Jean revealed in an interview that Homer and Marge would be separating, causing a minor Internet freakout. "In the premiere, it's discovered after all these years Homer has narcolepsy and it's an incredible strain on the marriage," he teased back in June. "Homer and Marge legally separate, and Homer falls in love with his pharmacist, who's voiced by Lena Dunham. We'll have cameos from the other women from Girls."

After headlines about a Simpsons "divorce," Jean later clarified his statements on Twitter. "What I said is correct/was completely misinterpreted as you will see 9/27," he wrote.

Check Dunham's scene in the clip above, then tune in for The Simpsons season 27 premiere on Sunday, Sept. 27 at 8 p.m. on Fox.
